Hi all-
Sorry, this is later than I had hoped to send this. This series has
three minor fixes for mpx and the instruction decoder.
Changes from v2:
- Dropped patch 1 (fixed in tip separately)
- Fixed comment typoes in patch 2 (noticed by Dave)
Changes from v1:
- Dropped the TIF_IA32 change
The instruction decoder used to assume that the input buffer was
exactly MAX_INSN_SIZE bytes long. Now that the input buffer has
variable length, even if the input buffer is longer than
MAX_INSN_SIZE, we should still reject instructions longer than
MAX_INSN_SIZE, since a real CPU will reject them
This reduces the degree to which we're exposing the instruction decoder
to malicious user code at very little complexity cost.

Each per bucket lock covers a configurable number of buckets. While
shrinking, two buckets in the old table contain entries for a single
bucket in the new table. We need to lock down both while linking.
Check if they are protected by different locks to avoid a recursive

An early preview release Git v2.3.0-rc0 is now available for
testing at the usual places.
With the slowness from the end-of-year holiday, this cycle turned
out to be a relatively lean one as I predicted (just 200 changes
since 2.2, as opposed to ~500 changes in an normal cycle), but that
is fine.
The latest maintenance release Git v2.2.2 is now available at
the usual places.
This backports many fixes that were not in 2.2.1 that have been used
on 'master' for the past few weeks.

Hi everyone,
I will be leaving Synopsys on Friday, Jan 16th, so the dwc2 driver
will need a new maintainer.
I am recommending John Youn as the new
maintainer.
On the plus side, John has quite a bit of experience with the dwc2
controller, and has previous experience submitting kernel patches
SCIF character device file operations and kernel APIs for opening and
closing a user and kernel mode SCIF endpoint. This patch also enables
binding to a SCIF port and listening for incoming SCIF connections.

Looks pretty nice to me, thanks. I had a bunch of relatively minor

This reduces the degree to which we're exposing the instruction decoder
to malicious user code at very little complexity cost.

The instruction decoder used to assume that the input buffer was
exactly MAX_INSN_SIZE bytes long. Now that the input buffer has
variable length, even if the input buffer is longer than
MAX_INSN_SIZE, we should still reject instructions longer than
MAX_INSN_SIZE, since a real CPU will reject them
If next_byte + sizeof(t) == end_kaddr, then we are trying to read
exactly to the end; this should be allowed.

Hi all-
Sorry, this is later than I had hoped to send this. This series has
three minor fixes for mpx and the instruction decoder.
Changes from v1:
- Dropped the TIF_IA32 change -- let's defer that until at least 3.20.
- Fixed the MPX decode short-circuit. v1 was buggy.
- Patch 3 is new.

Hi Felipe,
I've rebased that patch series but it depends on another one (the mfd:
syscon: part of "memory: add Atmel EBI (External Bus Interface) driver")
that is not taken yet so applying it now will break the build. I still
hope to get it merged for 3.20 and I'll resend it as soon as possible.

Wrap BUG() branches with unlikely() where it is possible. Use BUG_ON()
instead of "if () BUG();" where it is feasible.
